To all whom it may concern:

Be it known that I, RALPH J. SHIPLEY, of \Vaterbury, in the county ofNew Haven and State of Connecticut, have invented a new and 5 usefulImprovement in Machines for Making Metallic Paper-Fasteners; and thefollowing is declared to be a description of the same.

My present invention relates to a machine for bending and shaping ametal blank and I0 forming therefrom a metallic paper-fastener.

My improved machine is simple in construction and automatic andeffective in its operations.

The metallic blanks are fed from a containing-sheath one at a time by asliding feedblade upon the top of yielding jaws. A pin working through aslide-head is brought to place above the blank and is pulled down uponsaid blank, bending the same into a form.

The further movement of the pin downward draws the blank in between theends of the yielding jaws and bends the blank double, so that its prongsare parallel, or nearly so, and of a distance apart equal to thethickness of the pin. This pin and blank continue to move down betweenthe yielding jaws, and as the pin passes below said jaws they close bythe action of springs and bend the blank around the pin, forming a roundhead. This pin is then withdrawn and an ascending anvil strikes theround head and flattens it equally each side ofa perpendicularline.During this latter operation the pin is raised and projected overanother blank that has been meanwhile projected to place upon top of theyielding jaws. The downward movement of the pin in forming another blankopens the yielding jaws and releases the blank already made and it fallsout.

In the drawings, Figure 1 represents an elevation of my machine. Fig. 2is a plan view of the same. Fig. 3 is a vertical longitudinal section atmm of Figs. 1 and 2. Fig. 4 is an elevation of the receiver or sheathfor holding the blanks. Figs. 5 and 6 are detail views in larger size ofthe pin and secondary head. Figs. 7, S, 9, 10, and 11 are detail viewsshowing the various stages of bending the blank.

A is the main base-frame of the machine, and A its upright portion.

The shaft B for driving the mechanism is journaled in bearings upon theupright frame A, and said shaft carries the fly-wheel E, driving-clutchD, cams C C, and crank-wheel Q. The clutch D is connected anddisconnected by the clutch-lever D. A belt driven by suitable power isused upon the pulley ol' the clutch D to operate the machine. The connecting-rod R extends from the crank-wheel Q to a sliding head, P, inguide-slides O O in 6c the frame A to move the head up and down.

Upon the face of the sliding head I? is an anvil, P, and this anvil isshown as resting upon a bracket, which is a part of the sliding head,and said anvil is held to the head 1? by 6 a set-screw, 4, and isadjustable vertically by the set-screw P Upon the upper end of thesliding head P is a bracket-arm, S, and passing vertically through saidbracket-arm is a screw, T, that ;o is attached at its lower end to thesecondary head U, which is free to slide in guides in the frame A, andthejam-nuts on such screw connect it by and to the bracket S and causethe head U to be moved in unison with the sliding head P.

Upon the back of the secondary head U is a socket, 'V, one side of whichis slotted. (See Figs. 5 and 6.) Within the socket V isapinholder, W,and the pin X passes through this holder NV and through the heads U andP, and the frame A is slotted at a for this pin X. The screw Y passesthrough the holder W, and clamps the pin X in place; but said pin may beremoved or fed forward as worn.

There is a pin, 5, secured to the holder XV, and said pin passes throughthe slot in socket V and through the fork or slot of the lever Z, andthere is a nut, 6, and washer 7 connecting the holder WV and lever Z,the said pin 5 being free to move up and down in the forked or slottedend of the lever Z as thehead P and secondary head U are raised andlowered. This lever Z Z is pivoted at A to a lug of the frame A, and theend of this lever has a roller or frictionwheel, Z, which is acted on bythe cam C, which imparts to said lever and the pin X a forward motion,the retractile spring B imparting the return movement.

There is a bracketed table, F, secured to the frame A at its upper part,and upon said table is the slotted dovetailed block G, into which isreceived the dovetailed end of the blankholding sheath H, which isbrought to this forming-machine from the filling-machine, and is full ofmetal blanks for making the paperfasteners. An arm, h, Fig. 1, isemployed to clamp and hold the sheath H in the block G. The forward endof the table F is made with guidewaysff, in which works the slide-blockI. and to the block I is connected the feedblade J. This blade J ismoved back and forth above the table F and below the block G and betweenthe end guides, ff, and said blade takes the bottom blank from the pileof blanks in the slotted block G and delivers it to the bendingmechanism.

The slide-block I has an arm, 1, connecting it to the rod K and carriageK, and there is a lever, L, whose slotted upper end is connected by apin to the carriage K, and said lever L is pivoted at A to a lug uponthe frame A, and the end of the lever L carries a friction-roller, M,which is acted upon by a cam, 0, upon the driving-shaft B, to impart tothe carriage K, rod K, arm I, and pushingblade J a forward movement, aspring, N, retracting the lever L to deliver the blanks.

There are sliding stocks D D in the frame A,,and connected to them arethe jaws E E, which, with thestocks, can be moved horizontally. Thespring-arms F F are connected at their lower ends by bolts 8 to thesides of the upright frame A, and the upper ends of said springs bearagainst the outer ends of the stocks D D and act to press them and thejaws E toward each other, and tend to keep thejaws closed, but allowthem to be pressed apart.

Upon a pivot at 10 is the bent lever g g, and connected to it and to theframe A is the helical spring H. The upper end of this bent lever isslotted, and connected to it by the pivot-pin h is the clearer G. Thisclearer G passes through one bracket of the table F, and its bent endprojects over the anvil P. This clearer and bent lever are operated bythe slide-head P, the foot-piece of g passing under the lower side ofsaid slide-head P, so that the descent of the slide-head moves theclearer G forward, while its ascent allows the spring H to force thelever backward and move the clearer out of the way.

The operation of the machine in forming a paper-fastener from the blankis as follows: The metal blanks a from the sheath H and slotted block Gareremoved one at a time and delivered by the feed-blade J between theend gnides,ff, upon the upper edge of thejaws E E and beneath the pin X.The descent of the slidehcad P brings down the projecting pin X, as seenin Fig. 7, and said pin pressing the blank bends it into a V shape, asshown in .Fig. 8. The further movement of the pin X as it acts on therounding corner of the jaws opens them and bends the blank, as seen inFig. 9, and the pin and bent blank descend between the jaws, and as thepin X passes below the jaws they close upon the blank, bending it aroundthe pin and bringing its arms together hold itin place, as seen in Figs.1 and 10. The further movement of the mechanism now withdraws the pin X,leaving the blank held by thejaws E, and the slide-head P is raised, andthe anvil connected thereto is brought to bear upon the open round headof the blank and flattens the same into the form shown in Fig. 11, andat the same time the pin X has been raised with the heads and isprojected by the lever Z Z, and by this time another metal blank hasbeenpushed upon the upper edges of the jaws E by the feed-blade J, and theparts are again in the position shown in Fig. 7, ready, by the descentof the pin X, to form another fastener, which operation opens the jaws Eand releases the firstmade fastener, so that it is free to fall into areceptacle provided for the purpose.

In case the fasteners so formed should not fall away when released, butshould stick upon the anvil P, the clearer G, moving across the face ofthe anvil, acts to remove the fastener and cause it to fall into thereceptacle'provided for that purpose.
